Default Vaccum leak???

When I start my 1978 the headlights pop-up, after a few minutes they retract I think I have a vaccum leak somewhere where is the best place to start looking?

This is just a WAG, but I would guess the the actuators themselves are bad. I would also look at the linkage. If everything is right you should be able to turn off your car with the lights up and they should hold in the up position.

I had one act. go out. But the simptom was one side having a very slow rise.

Check the actuator relays first. If they are good, check the valves between the manifold fitting and the reserve tank.
